Question 10

What is the difference between API 610 and ASME B73.1 — and when does an FBCN meet both?

Accepted Answer

API 610 (Centrifugal Pumps for Petroleum, Petrochemical and Natural Gas Industries) is the American Petroleum Institute standard for refining, petrochemicals and gas — it demands more robust construction (mandatory back pull-out, oil-bath bearings, minimum MTBR, carbon-steel/stainless materials from class S6/S7 upward), extended pressure and temperature ranges and bench testing with ISO 21940 G2.5 balancing. ASME B73.1 (Horizontal End Suction Centrifugal Pumps for Chemical Process) is the American Society of Mechanical Engineers standard for chemical processing: it defines a standardized dimensional footprint (DN25 to DN300), hydraulic tolerances and ANSI flange — enabling cross-manufacturer retrofit. When the project requires dual compliance — common in refineries and chemical/petrochemical plants under Petrobras — the FBCN meets both simultaneously: API 610 12th ed. construction with ASME B73.1 dimensional, ANSI B16.1/B16.5 flanges, ISO 21940 G2.5 balancing and hydrostatic testing at 1.5× design pressure. Pure refining defaults to API 610; chemical/petrochemical defaults to ASME B73.1; Petrobras Oil & Gas projects layer both.

Question 11

Does the FBCN comply with ASME B73.1?

Accepted Answer

Yes. All 53 models in the FBCN line are built per ASME B73.1 — Specifications for Horizontal End Suction Centrifugal Pumps for Chemical Process. Simultaneous compliance with API 610 12th ed. (refining and petrochemical), flanges per ANSI B16.1 (cast iron Class 125/250), ANSI B16.5 (steel/stainless) or ASME B16.42 (ductile iron), part numbering per DIN EN 24250, ISO 21940 G2.5 dynamic balancing and hydraulic test bench. Each pump undergoes hydrostatic testing at 1.5× design pressure before shipping from Cabreúva-SP.

Question 12

Is the FBCN dimensionally compatible with DIN 24255?

Accepted Answer

FBCN construction follows ASME B73.1, the North American dimensional standard. For projects requiring compatibility with pumps dimensioned per DIN 24255 (European standards), FB Bombas' application engineering evaluates dimensional flange/footprint equivalence on a case-by-case basis. The company operates under product-level standards compliance (API 610 + ASME B73.1 + ISO 21940 G2.5), without ISO 9001 quality management certification.

Question 13

Does the FBCN comply with API 610 — which edition?

Accepted Answer

Yes. The FBCN line is designed per API 610 12th ed. — Centrifugal Pumps for Petroleum, Petrochemical and Natural Gas Industries. Covers flow up to 2,200 m³/h, head up to 138 m and temperature up to 260°C, with back pull-out construction, ISO 21940 G2.5 dynamic balancing and hydraulic test bench. FB Bombas is a CRCC Petrobras qualified supplier in Family 6 — Rotating Equipment, eligible for Brazilian Oil & Gas projects.

Question 14

Is FB Bombas qualified by CRCC Petrobras?

Accepted Answer

Yes. FB Bombas is a qualified supplier in Petrobras' Cadastro de Registro Cadastral de Contratados (CRCC) under Family 6 — Rotating Equipment, eligible to supply industrial pumps for Brazilian Oil & Gas projects. The company operates under active corporate registry 61.381.240/0001-78, publicly verifiable at Brazilian Federal Revenue, and has been in continuous operation under the same corporate identity since 1944.

Question 15

What is the FBCN lead time compared to an equivalent imported pump?

Accepted Answer

FBCN lead time is defined case by case by the application engineering team in Cabreúva-SP, considering the model (among 53 available), materials (cast iron FC-250, AISI 316, etc.) and specific configurations. Because manufacturing is fully Brazilian — in-house CNC machining, assembly and hydraulic test bench — lead times tend to be significantly shorter than equivalent imported pumps, with no dependency on international logistics, customs clearance or intercontinental transit time. Technical quotation available via the commercial form.

Question 16

How to request the technical quote and FBCN technical manual in PDF?

Accepted Answer

The FBCN technical quote is requested directly from the application engineering team. Provide flow (Q in m³/h), total head (H in m), operating temperature, fluid, available NPSH and desired materials. The FBCN technical manual — including Q×H×P curves, pressure×temperature table, construction dimensions and materials — is available at /en/technical-manuals/fbcn in Portuguese, English and Spanish, free for download in PDF.

Question 17

Which standards does the FBCN technical manual cite for construction, dimensioning and testing?

Accepted Answer

The FBCN technical manual (MTEC-03/00) defines the construction, dimensioning and testing specification of the line. The pump is dimensionally compliant with ASME B73.1 and mechanically compliant with ASME B73.1, with back-pull-out construction (allowing the bearing assembly to be removed from the volute without disconnecting the flange). The Hydrostatic Test Pressure is declared In accordance with ANSI B73.1. Flanges follow dual standardization: cast iron per ANSI B16.1 (125 Lb FF / 250 Lb FF) and steels or ductile iron per ANSI B16.5 or B16.42 (150 Lb RF). Part numbering per DIN EN 24250. These dimensional standards facilitate retrofit in existing installations that use normalized centrifugal pumps — standardized flange and footprint within the international catalog. The full manual with Q×H curves, per-component materials and construction details is available at /en/technical-manuals/fbcn in Portuguese, English and Spanish, free for download in PDF.

Question 18

What is a normalized centrifugal pump?

Accepted Answer

A normalized centrifugal pump follows standardized dimensions (footprint, shaft, flange) per standards like ASME B73.1, allowing interchangeability between different manufacturers. It simplifies retrofit without altering piping, baseplate or motor. FB Bombas FBCN series has 53 models (43 standard + 10 large frames) per ASME B73.1.

Question 19

What is the ASME B73.1 standard?

Accepted Answer

ASME B73.1 is the American technical standard that defines dimensional and mechanical specifications for horizontal chemical-process centrifugal pumps, with back pull-out construction and standardized flanges. It establishes interchangeability between standard-compliant manufacturers. FB Bombas FBCN series is fully ASME B73.1 compatible across all 53 models.

Question 20

What is back pull-out construction?

Accepted Answer

Back pull-out is the construction whereby the pump rotating assembly (impeller, shaft, bearing and sealing) can be removed for inspection or maintenance without disconnecting suction and discharge piping. It reduces maintenance time and risk to piping integrity. All 53 FB Bombas FBCN pumps implement back pull-out per ASME B73.1.
